The Development of the myKadera System for Object Vocabulary Mastery for Students with Hearing Impairment Based on Augmented Reality

Abstract

This study aims to: 1) design appropriate learning media based on Augmented Reality on the introduction of object vocabulary for hearing-impaired students, 2) perform the developed system. This research belongs to research and development (R&D). This developmental research refers to the stages of learning media development by Arief Sadiman, et al and the stages of the development model by Borg & Gall. This research development procedure consists of three major steps that must be passed, namely planning, development and evaluation activities. The result of this Android-based myKadera system development research is that the system has some features provided including audio, sign language videos, 3D animation, and object vocabulary quizzes that were packaged more interestingly, applicative and innovative with a more real-time visual display, supported by object vocabulary learning media books with the help of AR (augmented reality) markers. The results of the test indicate that the application meets ISO/IEC 25010 standards on aspects; (1) functional suitability; all features of the application has been successful and said to be good, which means there are no functions that fail on testing, ( 2) application compatibility; the application is 100% compatible with sub-characteristics of co-existence, various operating systems, and various types of devices used for testing, (3) performance efficiency; the application is successfully run using the AppAchhi test device. The application is said to be good without experiencing memory leak or application damage which results in force close or launch fail. The application shows an average time behavior of 0.063 seconds/thread, an average CPU usage of 20.39%, and average memory usage of 13.08 MB, and (4) usability testing obtained a percentage of 95.50%. These results indicate that the application is very feasible and meets the usability aspect.
